- Fast Open (Skip All) Opens a drawing quickly. No attempt is made to find or resolve any files referenced by the drawing. Once opened, the drawing behaves as though it had been opened with no file references present. You can open and save edits.

You can right-click the top browser node of a file containing unresolved files to initiate a Resolve File command. Clear the check box to resolve links on file open.
